'Homeland' Season 2 Teaser: Questions Will Be Answered (VIDEO)

"Homeland" Season 2 will be filled with answers ... hopefully. A new, spoiler-filled teaser from Showtime rehashes major Season 1 plot points and sets the stage for what should be an exhilarating Season 2.

Who has the video?
Brody was all set for a suicide mission that would have killed himself and a whole room full of government officials to smithereens. He even recorded his video farewell message.

Where is the vest? That aforementioned deadly explosion was going to come in the form of Brody's bomb vest.

Who is the mole? Somebody was leaking CIA info. Is it Saul? Estes?

What will Carrie remember? Carrie's knowledge is very powerful and is a key to stopping Brody's nefarious plans. But electric shock therapy messes with your brain.

Is it really over?
Can Carrie shake her feelings for Brody?

According to Showtime, all of those answers will be answered.

"Homeland" Season 2 premieres Sun., Sept. 30, 10 p.m. ET on Showtime.
